[Relation between certain parameters of renal function and prognosis in multiple myeloma]. / Povezanost nekih parametara renalne funkcije sa prognozom multipnog mijeloma.

BACKGROUND: Renal involvement is one of the most common manifestations of MM, with different pathogenetic mechanisms, like overproduction of monoclonal light chains and hypercalcemia, those are commonest precipitating factors for renal failure which occurs in nearly 25% of myeloma patients. Some renal pathology is noted in over half. METHODS: We studied retrospectively 16 patients with MM treated at Nephrology and Haemathology Clinic in Sarajevo, in the period from 1996-1999 y (10 females and 6 males). All fulfilled criteria for MM diagnosis: 1. Bone marrow involvement by greater than 20% plasma cells 2. Monoclonal paraprotein in the serum and/or urine 3. Lytic bone lesions. RESULTS: Appearance of high creatinine plasma level, red and white blood cells in urine, and proteinuria are the signs of renal function reduction. Renal failure was noted in 10/16, erythbruria 6/16, pyuria, 7/16 hyperuricemia in 8/16 and 3/16 (19%) were died during hemodialysis programme, and Bence-Jones protein was noted in urine with 7/16 (43%). Severe renal failure with 5/16 was noted and beside high plasma creatinine we found high plasma calcium and Bence Jones in urine. CONCLUSION: High plasma levels of creatinine and calcium and Bence-Jones in urine, are poor prognostic signs of MM.

[Occurrence of bacteriuria in malignant hematologic diseases]. / Ucestalost bakteriurije kod malignih hematoloskih oboljenja.

BACKGROUND: Infection risk with patients suffering from hematological malignant diseases is a result of an interaction between a patient and a host and of a dysfunction of organs. During the evolution, human beings have developed an effective defense mechanism. It was defined with functioning of: 1) skin and mucus membranes, 2) phagocyte cells and 3) humoral and cellular immunity. The patients with malignant hematological diseases are exposed to complex pathogenic processes that disturb their balance, which leads to the occurrence of an infective syndrome. METHODS: In the retrospective study of 422 patients with malign hematological disease, epidemiological-clinical analysis of the infectious syndrome has been carried out. Patients were hospitalized at the Clinic for Hematology--Clinical Center of Sarajevo University, in the period from January 1, 1993 to January 1, 2000. diagnostic protocol included the following procedures: anamnesis, clinical picture, biochemical, cytomorphological, pathohistological, microbiological and radiological test. The goal of work was to determine bacteriuria in case of malign hematological diseases as an accompanying, combined complication during the treatment of these patients. RESULTS: In case of patients that were hospitalized in 1994, bacteriuria was present in the percentage of 56, which is over expected trend line whereas in 2000 it was registered in 20.65% of patients had bacteriuria while 17% of patients had have infection, 28% of patients had bacteriuria while 17% of patients had other infections. In case of patients up to 65 age, bacteriuria was more frequent in female population while in the age of over 65 it was more frequent in male population. Through microbiological analysis of urinary flora, monomicrobial bacteriuria was found in case of 58% patients, and patients were mainly in the initial phase of disease. In case of patients with long treatment with antineoplastic drugs or in the phase of advanced basic process, bacteriurias with polymicrobial character were dominant, which is characteristic of recurrent infections of urinary tract. CONCLUSIONS: The authors came to the conclusion that it is necessary to monitor urine flora with malignant hematological disease patients and by using an adequate treatment to minimize initial infection, relapse and reinfection of urinary tract. Still, it is not clear which is the basic factor initiating the infection of urinary tract--whether it is the prevailing intensity and pathogenic aggressiveness of an agent, or the exposure intensity or a supportive condition of the patient.

[Clinical aspects of multiple myeloma]. / Klinicki aspekt multiplog mijeloma.

This paper is a review of the patients with multiple myeloma, hospitalized at Clinic of Haematology in Sarajevo during the period from 1993 to 1998. This study encircles 45 patients; 18 males (40%) and 27 females (60%). Clinical and laboratory records, etiology, cytomorphology and radiography were analyzed in detail. The age of patients was 59.4 years (both males and females). The trends of disease showed increasing in 1994, 1997 and 1998, comparing it with other haematological malignancies (in 1993 the percent was 5.41, in 1998 was 15.83, and the average level, during the analyzed period, was 11.34%). The patients usually came in the terminal phase and that is the reason why median survival was 12 months. According to the results, the authors make a conclusion that there are some characteristics of this disease in individuals, comparing them with the results shown in relevant studies. They find the explanation in the exposure of the population to the chronic stress and deficit of energy caused by malnutrition during the aggression against Bosnia and Herzegovina.
